only thing i can think of is the brass might be getting old now, I've had it for 3-4 years and probably shot them all no less than 8 times (Lapua) any other ideas
I let the barrel cool a bit between each shot - in that bottom group the flyer was the first shot of the day.

Clean tube? Don't stress sometimes we all just have shit days shooting paper

Yup. Don't think it is the brass either as the flier in each group would have to have the same issue looking at it.

Old instructor would say that being horizontal flyers trigger pull is to blame

Weigh your projectiles perhaps. Some batches of bullets are terribly inconsistent with weight. Another variable to check.

Thanks boys. Will have another go this weekend

To revisit this, ended up with 120gn pro hunters doing 2600fps groups are an honest .25-.5". I've only shot reds to 70m and fallow at 30m but it drops them like a sack of spuds. Range finder binos on the way so will be able to push the distance later.

Tried any N560 @Timmay ?

What powder do you run, I don't get that speed with 143g out of my 22"

Nah, I've never tried any powder other than ADI, as its the only stuff that I can easily get my hands on locally.

was sighting in hence the POI. Two shot groups @ 100m.

Na me neither and I have a factory R8 barrel- longer.
Accuracy is good using 140 amax and 2209. Want to try a different powder soon.

What about that RL19 stuff? that can give better velocity apparently.

Maybe in longer barrel lengths 20"+ I would imagine?

I don't reckon it's better to use a potent faster burning powder (and less of it) to achieve greater accuracy. Even tho you might not get really high velocity, loading fairly high with a magnum powder has yielded the greatest precision for me. Maybe try 2213 and see if it works. I also use that in my .243 and it also shows extremely tight 5 shot groups.
-This all stems from somebody's comment that an shot from a nearly full case will give a more repeatable Shockwave to the back of the projectile..... Seems to be on par so far. Could be bollocks tho

IMR 7828, and or RL22 - the 140 VLD has a shorter bearing surface and that helps veocity gain. (the 120 TTSX gets 2209)

(Should have kept that rifle dammit!)
